MSR Arctic Fuel Pump
« on: May 03, 2017, 10:30:39 am »
MSR has a new Arctic Fuel Pump: https://www.msrgear.com/stoves/arctic-fuel-pump

Might be useful for those who use MSR stoves for winter camping.  Note, it is not compatible with their Dragonfly stove.

From the website:

"Specifically engineered for use in temperatures below freezing, our Arctic Fuel Pump features extra-robust seals to prevent leaks in arctic conditions. It is field-maintainable and works with all MSR liquid-fuel stoves, except the Dragonfly® stove. Use only below 0° C (32°F)."

There could be a few reason for use only below 0, first could be the rubber compound would be super soft and in above freezing would wear faster. second the lubricant being super light could run out or into the fuel in warm temps... Just guessing here!

Look at the pump. Most of it is plastic. My guess is they have done a lot of testing and above 32 deg. there is a strong possibility that plastic parts of the pump will melt.

All the MSR pumps are plastic tho so I don't thing softening of the pump body is the issue

Leather washer and softer "O" rings is the answer
